iv rung around a few dealers and the 4agze blower is by far the easiest to get. Now is it to big to wak onto a 1275 induction wise?? and is it to big to fit under the bonet??? any one got one of these on thier bricks??

It's been done a few times. You can play around with pulleys and stuff, if it's pushing too much air in.

easiest to get???? na.....

if i remember right you're the adelaide boy...... go to JMS (Japanese Motorsport) down at 2 Rosberg Rd, Wingfield. They have shelves covered in turbos and superchargers. My Aisin charger was $190, and i had 40 to choose from and test.

u remember correctly.
timmy rang around a few places including a subaru wrecker who blatently told him there was never a 600cc blown subaru. then he rang a toyota wrecker and he said all he has is the mr12 mr14 chargers, but he did recall a subaru 600cc supercharger, but it was hard to get.


anyway wouldnt u say the supercharger for a 600cc engine is a little bit small for a 1300cc?
kinda why a mr12 supercharger sounds like the way to go.. :shock: :?

Mate I looked into the 4AgZe charger for my car and did a heap of research. It it a relatively efficient charger and you can fit it under the bonet. The only mod necessary is to grind a small part off your bulkhead approximately 20 cm long (to the left of your wiper motor. You then need to weld on a 45' angle of steel to allow for the charger to fit behind the head. If you try to bring it closer to the engine you suffer from decreasing the angle of the intake into the head and power suffers. I used a roots type blower as the exit is totally underneath and you can do a similar setup to fitting a downdraft carby. It allows you a more straight induction line and increases flow, and hence power. If you can find something similar you should be on your way. Hope this helps.

Bloody WANKERS - Some of these guys wouldnt know if their own ARSE was on fire....
Subaru Pleo, Vivio, and Rex VX660 - all 660cc, 4wd, injected AND supercharged. NEVER sold in Australia, but some were privately imported.

660 blower only ran at 8lbs boost, but is a easier unit to fit in a round nose bay - WITHOUT hacking the bulkhead. And I dont think its undersized.

Dont forget - you'll need to weld up the 4agze SC's clutch. If you dont, you will have timing problems when using a fixed distributor. The 4agze charger is usually fitted to a motor with 2 stage electronic ignition which switches the advance between BOOST and NO BOOST - both levels require different ignition timing to avoid killing your engine.

TRUST ME - i found out the hard way :wink:

Ah, fu(k it - TRY a 4agze blower if ya want - see if I care... :cry:

we were thinking about the no boost / boost switch. our mate runs a mr14 supercharger on his dato stanza, or at least i think its the mr14.
he says he has a control switch between no boost and boost.
but it's set at the ignition or something so that when he turns the car on the supercharger turns on.

i don't mind hacking into the bulkhead IF this doesnt cause any strength problems. i dont want my firewall caving in on me :P

i dont mind body modifcations to this car because its had the WHOLE FRONT CUT OFF :)
so i'll do my silly stuff to this car, and buy another round nose (down the track) and make it look schmick as a bee's bum. 8)

That boost on/off switch simply activates the clutch in the pulley. Its like an air-con switch. With it off, the clutch is deactivated, and the air con pulley spins freely. Turn the switch ON and the clutch locks ON to drive the unit.

Connected to the ignition key, the guy in the stanza is running boost at all times while the engine is running - key ON, clutch ON, supercharger ON. This setup uses alot of fuel, and requires only 1 ignition setup.

Normally on 4AGZE's, the SC boost switch is a vacuum sensor on the inlet manifold. When it senses a certain amount of vaccum, it switches the clutch on. At idle and steady cruising the boost is off, squeeze the throttle a little bit and it will still stay off, squeeze it a bit more and the increase in vacuum activates the switch, activates the clutch, and the car accelerates rapidly and instantly. This setup is very economical cos the blower only activates between mid to heavy acceleration. This setup requires 2 stages of ignition - basically 1x power, 1x economy.

im sorry economy? :lol:
im putting it in a mini, it'll never drink like a rotor so i think im in the win in that situation.

basically is it worth supercharging for the amount of power i'll be getting?
im a bit of a stooge and would only want to spend $2,000 on supercharging (the cost of the supercharger inlet pipes and custom manifold/brackets etc) not the strengthening and low comp pistons and what not, that goes under engine rebuild/performance :wink:

all up i want to spend $4k max :oops:
remembering im starting my apprenticeship so $5.90 an hour ain't to inviting :?

I'm working on fitting up a 4agze blower to my panel van right now - it's gonna cost me a lot less than $2k I can tell you that much - I've got friends who can weld alloy and can make me a pulley to drive it off the crank, but even if I was to get them custom made professionally it still wouldn't cost that much.

at $4k I'd *almost* be tempted to go to mini link and get them to do it - but I like to do things myself...

At Hay this year I met a bloke (Ben) who has made a few kits to fit these blowers, and he said he'd sell a kit for $800 (but don't hold me to that). I think he'll include the intlet manifold, decompression plate, front pulley, modified carb intake for the blower - not the blower, carb etc. I've got his number and pics of the install if u give me an email address - it's very neat. The car I looked at belonged to another guy and was running 7psi and was doing 90hp. Ben said his Mini is an 1100 running 14psi and 110hp

The key is getting the ignition right - gotta be electronic, and a high-output coil. I've heard that a V8 VN commodore coil does the job well, I'd be interested in what supercharged 850 is using for ignition.

by way of body mods - not necessary at all for the sc12 (correct name for 4agze blower) - the car I saw had the back of the bonnet propped up about 2", but it could be done with a bulge, no need to cut the bulkhead

i'm very interested in this kit, those few bits would make my life much easier. my email is [email protected] and im very keen for this guys number and photo's of his setup.

any info would be good.
i'd like to explore every avenue
and the bonnet buldge sounds wicked, i've got a fibreglass front that i dont mind modding to look like an xr8 bonnet :twisted:

Okay people, time for a lesson....

Anyone that props up the rear edge of the bonnet 2 inches WITHOUT using a front mount radiator is a GOD DAMN IDIOT.

A mini's cooling system works on the following principle...

Air goes in through the grille, air goes out through the radiator.

Jacking up the rear of your mini bonnet when having a standard radiator will lead to overheating and premature engine death, beacuse a majority of the air will be exiting through the gap at the back of your bonnet and NOT through the radiator.

Dont do this at home kiddies, unless you KNOW what you are doing.

hey supercharged 850 - I know the theory you're talking about with the air direction. What this guy has done is seal it along the back edge of the bonnet with a couple of pieces of rubber - attached to the rear lip of the bonnet and the top edge of the engine bay - they push together when the bonnet shuts, there are small gaps at the side - this guy ran in the motorkhanas all day with 3 people driving the car, and didn't have any heating problem - not that I saw anyway. He's got an alloy top rad tank, so is likely to be a 2 core jobbie of some description. Even running a mechanical fan - I dunno how it keeps cool either - some people are just lucky I guess.

If you're a member of hotbricks SA, chances are you'll know the car. Metallic blue, MINIAC plates.

I haven't decided whether I'll make a bulge, install a blanked-off poofter scoop and pretend I've got a hyundai excel, or raise the back edge... may end with a fibreglass bonnet

I'm curious about your ignition, and the induction length you've got on the carb side of the blower - was it a matter of the only place you could put the carb, or did you make it that long on purpose? please share some of your personal learnings

i like the way SC850's kept his car the shape it should be... the bonnet should only be open when you're on the side of the road, waiting for the RAA :)

And I'm sure they will be mighty helpful when you call them saying 'my supercharged mini 850 has broken down'. The NRMA's solution to my mates broken down Camry was to beat it with a BFH (No really! The fuel pump was broken!). That's what I woulda done I guess....
